UIP_Close is not sending the FIN , then how the connection from the TIVA host would be closed ?

Sanchit Mehra

Hi ,

TIVA C Series MCU - TM4C129NCPDT.

I have implemented web server on that, After sending the data, when the uip_acked() is called , I call the uip_close function to close the tcp connection.

But on wireshark, I couldnot see the FIN sent by TIVA, although the sender has closed the connection, but how can we close the connection on tiva side ?

Thanks,

Hi Amit,

The above problem is resolved .

But the other problem that I face usually is :

1. Sometimes , Connection is not being able to establish, in wireshark only SYN packets and SYN retransmissions are observed. and no SYNACK is replied by tiva.

2. On building the tiva firmware by optimization level 2/3 , the uip http application hangs and unable to respond.

Thanks,
